Description

The New-energy electric vehicle of electric connector and the application electric connector

Technical field

The present invention relates to electric connector fields, more particularly to a kind of heavy-current electric connector.

Background technique

Common jack contact has hat spring socket and torsional spring jack in heavy-current electric connector at present.Contact is in addition to passing Movement Capabilities determine except current-carrying capability and the thermal stability of electric connector that the robustness and durability of contact have further determined electricity The reliability and safety of connector.CN104538807A discloses a kind of hat spring socket contact, is easy to solve hat spring Device for elimination of axial-and radial-play occurs, electric current is caused to transmit unstable problem, using pressing ring or pin to the one or both ends of reed Interference fit is fixed.CN104505620A discloses a kind of high current jack contact, wherein in order to avoid hat spring is in vibration etc. The problem of loosening under situation, hat spring is interference fitted by being formed between end to end big outer diameter and current-carrying set, and is passed through Protheca is fixed.But both above-mentioned modes use pressing ring or individual pin separately manufacturing, and contact draws with pressing ring or independently The maximum of foot Elastic Contact, the resilient contact can be smaller with deformation quantity.When connector assembly does not have accurate guiding, it is easy The excessive deformation of resilient contact caused by occurring because of plug angle and journey error in turn results in the surrender damage of elastic component.Cause This above-mentioned hat spring socket and torsional spring jack are only applicable to the connector assembly of good guidance, are not particularly suited for plug environment, process The biggish application of error.

Summary of the invention

The purpose of this utility model is to provide a kind of connectors suitable for high current, to solve the big electricity of existing reed-type Stream connector pulls out that connect-disconnect life is low and the insecure problem of grafting in the occasion with axial angle insertion.It is above-mentioned to realize Purpose, present invention employs following technical solutions:

A kind of electric connector, including current-carrying set and contact pin, current-carrying set include first part and second part, and first Dividing has inner space, it is characterised in that: the first part is equipped with fluting, which forms the reed of cantilever beam structure.Institute The axis that reed is stated along the first part is obliquely installed by radial necking down process so as to according to different jack apertures school The normal pressure of positive contact point is thus it requires forming the contact pin of adaptation various sizes and optimize contact resistance and mechanical life The demand of electric connector.The first part for forming the reed can be pre-formed taper, then in the first part Fluting, to omit diameter reducing process.The current-carrying set directly forms current-carrying structures by the fluting reed, reduces and passes through hat Contact resistance caused by spring or the secondary adapter pin of torsional spring.

Further, the forward position of the reed is equipped with arcuate structure.The horn structure of the arcuate structure can inserted Needle provides guide function when being inserted into.The adjustable contact to the contact pin matched of shape and size for adjusting the arcuate structure is preferential Sequentially, while the arcuate structure improves the fault tolerance that contact pin imports, and improves the machinery and environmental longevity of the product.

Preferably, the front outsides of the reed are equipped with boss, pass through the insulation crust in the boss and connector assembly Inner wall cooperatively forms reed compression space and position limitation protection.It prevents from being mistakenly inserted reed excessive deformation caused by angle because larger and bending Clothes, improve the fault tolerance and robustness of the product.

Preferably, the front outsides of the reed can be equipped with shallow slot, and additional reed or bullet are equipped with by the shallow slot Spring, so that additional restraining force is provided for the reed, to reduce the contact resistance between the reed and contact pin and raising Mechanical life of the reed.

Preferably, the first part of the current-carrying set is equipped with more than two flutings, correspondingly forms more than two springs Piece, thus increase contact point and make up reed be adapted to contact pin it is non-it is superior guiding be inserted into when cannot be formed 360 ° electrical contact Problem.

Preferably, the second part of the current-carrying set is used for the connection of cable, and second part connects with a variety of cables Connecing mode includes being threadedly coupled, welding, crimping etc..When preferably, using crimping mode, the second part is equipped with several intervals The blind hole structure of the transverse groove of setting may be implemented to reduce crimping resistance and increase the function of cable retention.

Preferably, the first part of the current-carrying set and second part are integrated manufacture structure, simplify design of part, drop Low manufacturing cost.

The present invention forms unique cooperation by the reed with unique design structure and with current-carrying set and connector shell Mode, to realize contact engaging and separating force appropriate, lower contact resistance and very high mechanical life and the non-superior guiding of receiving are plugged Robustness, be particularly suitable for New-energy electric vehicle.

Specific embodiment

Fig. 1 shows the embodiment of electric connector 1 of the invention in a simplified schematic way.It includes current-carrying set 2, is carried Stream set 2 includes first part 2.1 and second part 2.2.The first part 2.1 and second part 2.2 are preferably integrally manufactured. There is inner space 4 to be equipped with 5 shapes of fluting in suitable position for receiving contact pin, the ontology of the first part for first part 2.1 At the reed 3 of cantilever beam structure, the forward position of the reed 3 is equipped with arcuate structure 8, passes through the loudspeaker of the arcuate structure 8 Structure can provide guide function when contact pin is inserted into and form effective electrical contact with contact pin 9.Referring to Fig. 1,3 front of reed Outside is equipped with boss 6, can be resisted against on the side wall 7 of the connector assembly insulator and form limit, to avoid because of mistake Big error enters angle and the excessive deformation of reed is caused to surrender, and the robustness of high current connector so can be improved and significantly mention Mechanical life of the height in non-superior guiding.

Two or more can be set along the axis direction of first part 2.1 in the fluting 5, so as in the axial direction Form more than two reeds 3.By the through slot 5, the reed 3 passes through radial necking down process along the axis of first part 2.1 It is obliquely installed so as to be adapted to various sizes thus it requires being formed according to the normal pressure of different jack aperture corrections contact point Contact pin and optimize contact resistance and mechanical life electric connector demand.In conjunction with the arcuate structure 8, whole circumference is formed Multi-angle Elastic Contact reduces contact electricity to can form electrical pickoff as much as possible within the scope of 360 ° with contact pin is adapted to Resistance guarantees effectively electrical contact.The first part 2.1 for forming the reed 3 can be pre-formed taper, then at described one point It slots on 2.1, to omit diameter reducing process.

Referring to Fig. 3, the front outsides of the reed 3 can be equipped with shallow slot, by the shallow slot be equipped with additional reed or Spring 10, to provide additional restraining force for the reed, to reduce contact resistance between the reed and contact pin simultaneously Improve the mechanical life of the reed.Referring to fig. 4, the second part 2.2 of the current-carrying set 2, is formed using machining Blind hole structure 12 equipped with several spaced transverse grooves 11 can also pass through screw thread, it can be achieved that cable is crimped with what current-carrying covered And welding manner carries out cable connection.

Electric connector of the invention is preferred for electric car, embodiment described in book and attached drawing described above, can be with Conventional deformation including this field, such as the other selections of the type of reed.
